Am I right in thinking that the term "weight" in your examples has nothing to do with the probabilities of a particular weapon or prefix being chosen, but rather the in-game strength or effectiveness of the composite weapon?

Ie. It is not your intention that 'acid' should be chosen twice as frequently as 'fire' or 'frost'?

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.

"Science is about questioning the status quo. Questioning authority".

In the absence of evidence, opinion is indistinguishable from prejudice.
